Additional information: It would be really cool if this kind of technology as well as other motoring enhancements will be easy to access in a near future by any citizen not only to be shown in car showrooms. But the hovercraft technology comes with several problems; for example, you cannot break because there is no friction with the earth whatsoever. Plus, what if there's wind and it just blows the car of the road... But they'll find a way to rectify this, I'm sure.
